BRAKE AND METER CONSTRUCTION.

Application filed March 13, 1924. Serial No. 698,860.

To all whom it may concern:

Be it known that I, Anrni. Y. Down, a citizen of the United States, residing at South Bend, in the county of St. Joseph 'and State of Indiana, have invented new and useful Improvements in Brake and Meter Constructions, of which the following 'is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming apart of this specification.

My invention relates to brake and meter construction for automobiles. m

' ()ne of theobjects of my invention 18 to provide means whereby the meter of a taxicab may bedriven from the front wheel and atthe same time the front wheel may be i provided with a brake.

the construction shown in Further objects will appear from the de scription and claims. 1 In'the drawings, in which two forms of my invention are shown I Figure 1 is a horizontal view showing the steering knuckle, brake drum, and associated P 3 -Fig. 2 is a perspective view of the brake drum; 1

Fig. 3 isan elevational View of-t-he brake drum showing the pinion and meter shaft;

Fig. 4 is a perspective view'showing'a difierent form of brake, and

Fig. 5 is a fragmentary sectional view of Fig. 4.

In taxicab work it is sometimes desirable that the meter should be driven from the front wheel, as the rear wheels are subject to slippage and the meter driven from the rear 'heel or from the propeller shaft would I not register the milagc correctly. It is also desirable that the front wheels as well as the rear wheels be equipped with brakes. To accomplish these two results, I mount a brake drum to turn with the front wheeland drive the meter from this brake drum.

Referring-v to the construction shown in Figs. 1, 2 and 3, this comprises the front axle 10. a steering knuckle 11, pivotally mounted (ill the axle by means of the steering knuckle pin 12, the front'wheel-hub 13 mounted on the axle 14, which extends from on sai the steering knuckle 11, a brake drum 15 secured to the-huh 13, internal brake means 16, hearing on the inner surface of the brake d-riun, a worm pinion l7 driven from the brake drum and a flexible shaft 18 driven from the pinion 1T.

'lhc pinion 17 is driven from the brake drum by iueans=of helical threads 19 on the outer surface of the brake drum, which' llll'GtltlSjfOllll a worm gear. These helical threads also act as heat radiating ribs and may be die-cast with the brake drum.-

'lhe pinion 17 is mounted on a stub shaft in supported in a bearing bracket 21 which in turn is adjustably mounted on the bracket 22 secured at 23 to the steering knuckle 11.

in Figs. 4. and 5 isshown a somewhat different form which can be used with an In this form, theexterual type of brake. meter nnon 17 is driven from a ring gear 2i having a. spiral thread 25 secured to the inner fuceof the brake drum 26, In order to permit drainage of the brake drum in case water should get splashed-into it, the spiral gear is spaced somewhat from the inner face of the drum by means of washers 27 through which the securing bolts 28 extend. v I

This construction and arrangement of the meter drive permits the use of external brake hands 29. v

While 1 have shown but two forms of my invention, it is obvious that it me be embollied in other forms covered an defined by the claims.

H aving thus described my invention, what I claim as new and desire to secure by Letters Patent ot-the United States is 1. A brake and meter construction com prisin an axle,.a steering knuckle mounted axle, a road engaging wheel mounted on said steering kn'uek1e,'a brake drum mounted to turn with said wheel, a meter shaft. and transmission means for driving said nieter'shaft from said brake drum com-' prising a pinion mounted on said shaft, and a worm on said brake drum meshing wlth said pinion, said worm comprising a Ilb extending circumferentially' with respect to said, brake drum and located on the periphing material and serving as a heat radiating mamber.

2. An automobile brake '(l'ium having a circumferentiully-extending heat-radiatmg warp: thread at its 3. '..ii automobile geri m belly.

G (1mm having a cylindrical braking flange and a circumferentially-extending heat-radiating worm thread on the xtenpr of said flange.

In witness whereof, I have hereunto subscribed myname.
